Respuesta :

To find the surface area of this rectangular prism, you need to find the area of all six faces. The front and back faces have an area of square unit(8x5) each totaling 80 square units. The side faces have an area of 25 square units(5x5) each totaling 50 square units and the top and bottom of the rectangular prism have areas of 40 square units each totaling 80 square units. Adding all these together (80 + 80 + 50) gives us the total surface area of 210 square units.

The surface area of the given three-dimensional figure is 210 square units.

Option A will be the correct answer.

Surface Area of Cuboid

A cuboid is a three-dimensional figure having length, width and height. The surface area of a cuboid can be calculated by adding together the areas of the six faces.

For the given cuboid, length l = 8 , width w = 5 and height h = 5.

Area of Cuboid  =  2 lw + 2 lh + 2 wh

[tex]A = 2\times l\times w + 2 \times l\times h + 2\times w\times h[/tex]

Substituting the values in the above formula, the area will be,

[tex]A = 2 \times 8 \times 5 + 2 \times 8 \times 5 + 2\times 5\times 5[/tex]

[tex]A = 210 \;\rm {units}^2[/tex]

Hence, the surface area of the cuboid is 210 square units.
